Te absolvo...

The President of the United States can ex officio grant pardons.  This is something which traditionally, outgoing Presidents do - if at all -  as a final act of their presidency.  But of course, Trump is not your standard President.  He has talked about pardoning Mohammed Ali, despite their being no offence for which to pardon him.  Even more bizarrely, he is considering pardoning himself - even though, as he himself says - he has done nothing wrong. Funny old world these days, isn't it?
